Sawadee ka Keri,
First off, all the very best for your wee Thailand adventure! Very exciting.
I had my SRS with Chet on 22 December (Christmas in the clinic!) so 7 weeks post-op. They had me on Tramadol while in the clinic and gave me anti-biotic, anti-swelling drugs, Tramadol and paracetemol when I was discharged to the hotel. I used a few of the paracetemol just to dull the discomfort at night for a couple of days but left the Tramadol alone and gave them back. I didn't feel I needed much pain relief. I imagine that if you do and run out, Chet's team will see what can be done for you. They are just a phone call away and visit every day except Sunday.
I was by myself and apart from being alone, I didn't feel I needed anyone to assist. I could get food, move about when I had to even before the catheter was removed (it was kept in for a week after being unpacked so it was in for a while - there were reasons!). I was going down to breakfast every morning with the catheter bag hooked up under my skirt.
There is a list somewhere on here of things to take. The clinic give you 1 pack of pads so stock up on those or buy more from Sri when she visits. She will bring them the next day. Everything is available in Bangkok so you don't need to buy them before travelling. I am not sure where you are staying but even if nobody is around to do a shop run, if you aren't up for a walk to shop, you can order supermarket stuff from Tescos online and get it delivered for the hefty fee of 60 Baht (a dollar or 2!). I think all 3 hotels are in the delivery zone. I did this mainly for drinking water as the hotel (Vertical Suites) only provided 1 litre per day. I didn't want to carry that back in the Bangkok heat. I got lots delivered.
I also used Chet's letter to get a wheelchair at the airport going home. Even though I could have managed as walking wasn't an issue, it was a very good idea. Got ushered through all the checks and delivered to an airline lounge and then he came back and wheeled me to the aircraft door! First on the plane. The time from leaving the hotel with Chet's driver to sitting down in the Emirates lounge was 60 minutes.
Have a super time in Bangkok.
